IMPROVEMENT IN BED-SPRINGS.

Specification forming part of Letters Patent No. 184.899, dated November 28, 1876; application filed April 1, 1876.

To all whom tt may concern:

Be it known that I, GEORGE PIRRUNG, of

. Ravenswood, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Spring Bed-Bottoms, of which the following is a specification:

The head and foot supports for the slatted bottom are each composed of a separate frame, consisting of a base-bar, A, upon which the slat-bar O is supported edgewise in a peculiar manner to afford a yielding action, so that the head and foot frames are not connected except by the slats. The slat-supporting bar 0 of each frame is connected to the base-bar A by two spring-bars, B, which cross each other on opposite sides of the bar 0 and parallel therewith. These spring-bars B are secured at their lower ends A to the base-bar, and at their upper ends to the slat-bar G by bolts 12 passing through slots a in said edgewise-arranged bars 0, a fulcrumblock, B, being secured upon the base-bar at the crossing of the spring-bars to support them. By having the spring-bars arranged on opposite sides of the edgewise-placed slatbars 0 the latter are braced in position to the base-bar, and allowed to yield vertically between the elevated ends of said spring-bars, the slots aadmitting of such movement.

By this construction the head and foot frames are separate and distinct-from each other, and when placed in position are connected by the slats, so that they can be easily removed for cleaning.

The slat-bars 0 being placed edgewise between the spring-bars admits of a compact arrangement, and of their being placed across the head and foot of any ordinary bedstead, and the bed prepared upon the slats supported by them. Spiral springs D may be placed under each end of the bars 0, if desired 5 but the spring-bars D, being of wood, are sufficient- 1y strong to give the proper support and yielding action. In some cases these end springs might be preferable, and I intend to construct the head and foot frames with and without them.

These separate frames are small enough to be set upon the bedstead-frame, and the slats placed thereon hold them in position by pins 0 at the top edges of the bars.

In the accompanying drawings, Figure 1 represents a side view of one of the supporting end frames for the bed-bottom; Fig. 2, a top view of a portion of the same with some of the slats in place, and Fig. 3am end view of the same.

It is' not new, broadly, to combine crossed spring-bars with a slat foundation, nor the combination, with such crossed spring-bars, of a fulcrum-bar and spiral springs; but in such combination the cross spring-bars form the sides of a bed-bottom frame of which the slats are a part, and supported and connected to the inner ends of the cross spring-bars by spiral springs, and in which both ends of said spring-bars are free to rise and fall, whereas by my construction this result is impossible.

I claim 1. The bars 0, arranged edgewise between the spring-bars B, and with the base A, forming the separate spring-frame described, and combined for use with the slats, in the manner and for the purpose specified.

2. In a spring bed-bottom, the bars A O of the separate head and foot frames, provided each with crossspring-bars B, the bolts and slots a, b, and the fulcrum-block B, all combined for use with the slats, in the manner shown and specified.

The above specification signed by me this 2d day of March, 1876.

GEORGE PIRRUNG.
